public void beginGroup(java.lang.Object object, boolean asNode)
VolumeListener
SceneVisitor
when subsequent
volumes shall be grouped into a single compound object. The group
extends until the corresponding invocation of VolumeListener.endGroup()
.
These invocations may be nested, i.e., there may be groups within
groups.
Each group starts at object
in the graph. If
object
has a geometric representation itself, the
corresponding invocation of VolumeListener.volumeCreated(java.lang.Object, boolean, de.grogra.vecmath.geom.Volume)
may be either
immediately before of after beginGroup
.
